Slide ring seal assembly

Abstract

A slide ring seal assembly comprises at least one pair of interacting slide rings (4, 5) of which one is provided for mounting on a stationary part and the other is provided for rotating together with a rotating part and of which one is mounted in a manner that enables it to axially move and is axially pretensioned with a designated axial pretensioning force against the other slide ring by means of a spring bellows assembly (11). This spring bellows assembly comprises a first spring bellows (13) that, at one end, are supported on the respective slide ring and, at the other end, are supported on an annular divider element (12) mounted in a manner that enables it to axially move relative to the respective part, and comprises a second spring bellows (14) that, at one end, are supported on said divider element and, at the other end, are supported on the respective part. The divider element (12) can move counter to an axial frictional force relative to the respective part, said axial frictional force being at least equal to a designated maximum operating vibratory force. Vibrations are prevented from being transferred to the second spring bellows so that only the first spring bellows are subjected to vibratory stresses.
